Anthracene, hydrogenation

A more complex reaction model was proposed from the results of a kinetic study of thermal liquefaction of subbituminous coal. Data were obtained over a temperature range of 673 to 743 K (752 to 878°F) at 13.8 MPa (2000 psia) by using two solvents, hydrogenated anthracene oil (HAO), and hydrogenated phenanthrene oil (HPO), at a coal-solvent ratio of 1 15. Results were correlated with the following model ... 

About one half of the coal samples used in the above study (61) have been investigated by workers in Gulf Research and Development Company, using a continuous flow reactor (63). The throughput was about 1 kg./h of coal/solvent slurry, the solvent was a partly hydrogenated anthracene oil, temperatures of 440 and 455°C were used, and the system was pressurized with hydrogen to 20.69 MPa. 

It was found that the Et3SiH and boron trifluoride monohydrate (a strong acid compatible with Et3SiH) ionic hydrogenation system produces partially hydrogenated anthracene [Eq. (11.77)] and naphthacene in excellent yield under mild conditions 240... 

Feedstocks - The vapors from the carbonization of a bituminous, low-rank coal, an anthracene oil, and a coal extract in anthracene oil were diluted with nitrogen and cracked their product yields were compared with those from the cracking of a partially hydrogenated anthracene oil and coal extracts hydrogenated to various extents. The coal was Linby (National Coal... 

Four model compounds, n-undecane, tetralin, cis/trans decalin and mesitylene, and a natural gas condensate from the North Sea were also cracked. Analyses and the reference code key of the coal-based feedstocks and the gas condensate are given in Table 1. Paraffin, naphthene, and aromatic-type analyses were calculated from gas chromatographic analyses of the partially hydrogenated anthracene oil and gas condensate whereas, mass spectrometric analysis was performed on the two coal extract hydrogenates and their further hydrogenated products. 

The yields from the partially hydrogenated anthracene oil (Cl), also given in Table 2, are relatively low, little more than 10% BTX and ethylene being obtained.
